Identifies 10 differences between scientific and artistic approaches to qualitative research: (1) forms of representation employed; (2) criteria for appraisal; (3) points of focus; (4) the nature of generalization; (5) the role of form; (6) degree of license allowed; (7) interest in prediction and control; (8) sources of data; (9) basis of…

Discusses five issues that deal with science and the citizen. These issues are: (1) nuclear weapons as a political problem, (2) group therapy, (3) microbroadcasting, (4) disentangling alliance, and (5) stinging cells in fish. (HM)

Presents the views of a high school physics teacher toward The International System of Units (SI). (HM)

Presents the author's perspective for accepting an approximation to The International System of Units (SI). Some alternatives to the SI form are also presented. (HM)

Discusses the theory, formation, and properties of the black holes, nature's dark stars. The connection between black holes and thermodynamics is also discussed. (HM)

In a brief Bicentennial retrospect author attempts to make a modest recreation of the years 1776 and 1876 and to summarize the last century's events in science and technology, with emphasis on chemistry, not only in the U.S., but also abroad. (Author/RK)

Presents pictorial analogies of several concepts relating to solutions for chemistry students. These include concentration of solution, strength of solution, supersaturated solution, and conjugate acid-base pairs. Among the examples are comparison of acid strength to percentage of strong soldiers or making supersaturated solution analogous to a…

Presents an exercise that involves construction of a model by high school students to demonstrate respiratory mechanics. Engages students in interactive learning and stimulates interest for future science study. Challenges students and teachers to build, manipulate, and discuss their experience during the investigation of respiratory mechanics.…

Presents an experiment designed to give students some experience with photochemistry, electrochemistry, and basic theories about semiconductors. Uses a liquid-junction solar cell and illustrates some fundamental physical and chemical principles related to light and electricity interconversion as well as the properties of semiconductors. (JRH)

Describes the construction of a sturdy earthworm box that can provide students with firsthand experience with earthworms. Presents activities that enable students to observe earthworms and discover how they enrich the soil. (JRH)

Presents a demonstration that illustrates charge conservation. Involves enclosing both the Teflon and the fur in metal tubes and measuring the voltage. (JRH)

Presents different methods for teaching animal classification to young children. Discusses modeling, observation, and the use of Venn diagrams among other approaches. (NB)

Suggests the importance of finding a way back from the scientific conception of education to an alternative, humanistic understanding, noting that the scientific concept applies general positivist and utilitarian principles to education. Suggests that the teacher-student relationship cannot be scientific, and teachers must view students as fellow…

Investigates preservice elementary teachers' responses to a concept attainment task using videodisk pictures and line drawings. Findings indicate that students using videodisk pictures used inferences to construct patterns while students using line drawings in connection with pictures significantly made more observations and developed fewer ideas…
